Do these oops etc. have anything to do with perf itself or rather with
persistence or non-persistence not properly supported with GuC? We should
have seen such failures with persistence tests (with GuC) itself so I am
wondering if there's any point of dragging perf into these already muddy
waters? Such failures should be isolated first with other tests without
mixing perf into this IMO.

Thanks.
